Timbren BES Disc Brake Pad & Rotor Kit OnyxBond

2019–2026 Ram 3500 6.7L Diesel

Part #: BES-14RB016

Overview

The Timbren BES Disc Brake Pad & Rotor Kit with OnyxBond™ technology is engineered specifically for the demanding rear braking system of the 2019–2026 Ram 3500 equipped with the 6.7L diesel engine. Designed to withstand the rigors of heavy-duty towing and hauling, this kit addresses the most common brake failure issues caused by excessive heat and corrosion. Whether you’re transporting heavy equipment, campers, or navigating tough job site conditions, this kit ensures reliable, consistent braking performance under extreme stress.

Ideal for professional drivers and serious truck owners, the Timbren BES kit upgrades your factory braking components with rotors and pads built to resist warping, brake fade, and pedal pulsation. This direct-fit replacement kit offers a straightforward installation process, making it an excellent choice for those seeking enhanced durability and safety without complicated modifications.

Key Features

Every component in this kit is designed to improve braking reliability and longevity in severe-duty applications. Key features include:

• OnyxBond™ Coating: Proprietary matte black finish rated to withstand temperatures up to 932°F, providing a 67% higher heat threshold than standard zinc coatings.
• Superior Heat Management: Engineered to reduce thermal stress, preventing rotor warping and brake fade during heavy towing or repeated stops.
• Fly-Cut Balanced Rotors: Precision-machined to eliminate vibrations and brake shudder for smooth, confident stops.
• Corrosion Resistance: OnyxBond™ layer protects against rust, road salt, and moisture, preserving cooling vanes and extending rotor life.
• Direct Fit Replacement: Designed to match factory specifications for easy installation without modifications.
• Severe-Duty Durability: Built to handle the demands of commercial and heavy-duty use, ensuring long-lasting performance.

Construction & Design

The Timbren BES rotors are crafted from premium-grade cast iron, optimized for thermal conductivity and structural integrity. The OnyxBond™ coating is applied using a proprietary process that bonds a matte black finish to the rotor surface, creating a robust barrier against heat and corrosion. This finish not only enhances durability but also maintains the rotor’s cooling efficiency by keeping vanes free from rust and debris.

Each rotor undergoes fly-cut balancing, a precision machining step that ensures uniform weight distribution and eliminates the vibrations commonly experienced during high-torque braking. The brake pads included in the kit are formulated for severe-duty use, providing consistent friction and fade resistance under heavy loads.

Installation & Fitment

This kit is a direct-fit replacement for the rear brakes on 2019 through 2026 Ram 3500 trucks equipped with the 6.7L diesel engine. Installation is straightforward and designed to match factory mounting points and hardware, requiring no special tools or modifications. This allows for a quick upgrade that restores and enhances braking performance, making it ideal for both professional mechanics and experienced DIY enthusiasts.

What's Included

• Rear Disc Brake Rotors with OnyxBond™ coating
